WE’VE all seen stressed parents at the security checkpoint, unloading babies from buggies, folding buggies the size of small excavators, with a baby in one arm and a screaming toddler at their feet. Next they are asked to open all of the pre-made baby’s bottles, then to remove their shoes and belts while still holding the children who are both screaming at this stage. Not a pretty sight but that’s the price of security these days.
